SyncEvolution 1.4 released#
The 1.4 release of SyncEvolution replaces 1.3.2 as the stable, supported release. 1.4 is the first stable version with the in-vehicle infotainment (IVI) PIM Manager included. GENIVI Diagnostic Log and Trace (DLT) is also supported. For more information about this aspect of SyncEvolution, see the PBAP and PIM entries in the [1.3.99 release notes](http://cgit.freedesktop.org/SyncEvolution/syncevolution/tree/NEWS?id=syncevolution-1-3-99-7) and these [Automotive Linux Summit slides](https://syncevolution.org/blogs/pohly/2013/pim-its-all-about-contacts). The biggest change for normal Linux users is Google CalDAV/CardDAV authentication with OAuth2. These are the open protocol that Google currently supports and thus the recommended way of syncing with Google, replacing ActiveSync and SyncML (both no longer available to all Google customers).
Support for Google CardDAV is new. Like Evolution, SyncEvolution does not yet support some of the advanced features of the server, in particular custom labels for phone numbers, emails and addresses. Likewise, some client properties are not supported by the server: CALURI, CATEGORIES, FBURL, GEO and ROLE are not supported. Of ORG, only the first two components are supported. Currently, properties not supported by one side get lost in a full roundtrip sync. Instant Messaging information is supported by both sides with different vCard extensions; the server stores these extensions without showing the information, while SyncEvolution drops the data sent by the server. SyncEvolution depends on external components for OAuth2. It can be compiled to use [gSSO](https://01.org/gsso) or GNOME Online Accounts. The latter is enabled in binaries from syncevolution.org. GNOME Online Accounts >= 3.10 works out of the box for CalDAV and CardDAV. 3.8 is guaranteed to work for CalDAV and may also work for CardDAV, if the Linux distribution ships a patched version (like Debian Testing/Jessie does). If it does not, then GNOME Online Accounts 3.8 binary can be patched to also support CardDAV, see the GOA README. Anything older than 3.8 does not work. Support for Ubuntu Online Accounts is available when compiling from source. For setup instructions see the [GOA](http://cgit.freedesktop.org/SyncEvolution/syncevolution/plain/src/backends/goa/README) and [signon](http://cgit.freedesktop.org/SyncEvolution/syncevolution/plain/src/backends/signon/README) READMEs. Binary packages of 1.4 on syncevolution.org have enhanced support for recent distros. They now work with EDS >= 3.6 *and* < 3.6. Distros with libical1 like Ubuntu Saucy are also supported. The HTTP server became better at handling message resends when the server is slow with processing a message. The server is able to keep a sync session alive while loading the initial data set by sending acknowledgment replies before the client times out. Some issues in CalDAV, WebDAV and SyncML were fixed. Graham R. Cobb contributed several patches for enhancing ActiveSync support and making it work with Exchange 2010. Guido Günther provided some patches addressing problems when compiling SyncEvolution for Maemo.
Details:#
D-Bus server: support DLT ([FDO #66769](https://bugs.freedesktop.org/show_bug.cgi?id=66769)) Diagnostic Log and Trace (DLT) manages a sequence of log messages, with remote controllable level of detail. SyncEvolution optionally (can be chosen at compile time and again at runtime) uses DLT instead of its own syncevolution-log.html files. See README-DLT.rst for more information. To use the feature, configure SyncEvolution with “–enable-dbus-server=–dlt –no-syslog”
D-Bus server: fix abort when mixing auto-sync and manual operations ([FDO #73562](https://bugs.freedesktop.org/show_bug.cgi?id=73562)) When enabling auto-sync for a config and then accessing or syncing the config manually via the command line tool, the server would abort at the time when the auto-sync was originally scheduled.
D-Bus server: accept WBXML with charset in incoming connections A user reported via email that the Nokia 515 sends ‘application/vnd.syncml+wbxml; charset=UTF-8’ as type of its messages this tripped up the syncevo-http-server, leading to: [ERROR] syncevo-dbus-server: /org/syncevolution/Server: message type ‘application/vnd.syncml+wbxml; charset=UTF-8’ not supported for starting a sync
D-Bus server: command line options for controlling output and startup The system log is used by default now. New command line options can be used to change this:
-d, --duration=seconds/'unlimited' Shut down automatically when idle for this duration (default 300 seconds) -v, --verbosity=level Choose amount of output, 0 = no output, 1 = errors, 2 = info, 3 = debug; default is 1. --dbus-verbosity=level Choose amount of output via D-Bus signals, 0 = no output, 1 = errors, 2 = info, 3 = debug; default is 2. -o, --stdout Enable printing to stdout (result of operations) and stderr (errors/info/debug). -s, --no-syslog Disable printing to syslog. -p, --start-pim Activate the PIM Manager (= unified address book) immediately.
D-Bus: missing out parameters in D-Bus introspection XML ([FDO #57292](https://bugs.freedesktop.org/show_bug.cgi?id=57292)) The problem was in the C++ D-Bus binding. If the method that gets bound to D-Bus returns a value, that value was ignored in the signature: int foo() => no out parameter It works when the method was declared as having a retval: void foo (int &result) => integer out parameter This problem existed for both the libdbus and the GIO D-Bus bindings. In SyncEvolution it affected methods like GetVersions().
D-Bus server: avoid progress outside of 0-100% range For example in the new TestLocalCache.testItemDelete100, the percentage value in the ProgressChanged signal become larger than 100 and then revert to 100 at the end of the sync. Seems the underlying calculation is faulty or simply inaccurate. This is not fixed. Instead the result is just clipped to the valid range.
sync: less verbose output, shorter runtime For each incoming change, one INFO line with “received x[/out of y]” was printed, immediately followed by another line with total counts “added x, updated y, removed z”. For each outgoing change, a “sent x[/out of y]” was printed. In addition, these changes were forwarded to the D-Bus server where a “percent complete” was calculated and broadcasted to clients. All of that caused a very high overhead for every single change, even if the actual logging was off. The syncevo-dbus-server was constantly consuming CPU time during a sync when it should have been mostly idle. To avoid this overhead, the updated received/sent numbers that come from the Synthesis engine are now cached and only processed when done with a SyncML message or some other event happens (whatever happens first). To keep the implementation simple, the “added x, updated y, removed z” information is ignored completely and no longer appears in the output.
command line: implement –create/remove-database Creating a database is only possible with a chosen name. The UID is chosen automatically by the storage. Only implemented in the EDS backend.
command line: execute –export and –print-items while the source is still reading Instead of reading all item IDs, then iterating over them, process each new ID as soon as it is available. With sources that support incremental reading (only the PBAP source at the moment) that provides output sooner and is a bit more memory efficient.
command line: recover from slow sync with new sync modes The error message for an unexpected slow sync still mentioned the old and obsolete “refresh-from-client/server” sync modes. Better mention “refresh-from-local/remote”. * command line: show backend error when listing databases fails The command line swallowed errors thrown by the backend while listing databases. Instead it just showed “
: backend failed”. The goal was to not distract users who accidentally access a non-functional backend. But the result is that operations like –configure or –print-databases could fail without giving the user any hint about the root cause of the issue. Now the error explanation in all its gory details is included. For example, not having activesyncd running leads to: INFO] eas_contact: backend failed: fetching folder list: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.meego.activesyncd was not provided by any .service files And running activesyncd without the necessary gconf keys shows up as: [INFO] eas_contact: backend failed: fetching folder list: GDBus.Error:org.meego.activesyncd.Error.AccountNotFound: Failed to find account [syncevolution@lists.intel.com] password handling: fix usage of GNOME Keyring and KWallet ([FDO #66110](https://bugs.freedesktop.org/show_bug.cgi?id=66110)) When clients like the GTK sync-ui stored a password, it was always stored as plain text in the config.ini file by the syncevo-dbus-server. The necessary code for redirecting the password storage in a keyring (GNOME or KWallet) simply wasn’t called in that case. The command line tool, even when using the D-Bus server to run the operation, had the necessary code active and thus was not affected. Now all SyncEvolution components use the same default: use safe password storage if either GNOME Keyring or KWallet were enabled during compilation, don’t use it if not. Fixing this revealed other problems, like not being able to store certain passwords that lacked the necessary lookup criteria (like syncURL and/or username). To address this, the lookup criteria where extended and a new check was added to avoid accidentally removing other passwords. As a result, it may be possible that SyncEvolution no longer finds passwords that were stored with older versions of SyncEvolution. In such a case the passwords must be set again.
GNOME: clean up keyring access and require libgnome-keyring >= 2.20 The updated error messages now always include information about the password and libgnome-keyring error texts. A workaround is used for the “Error communicating with gnome-keyring-daemon” problem that started to appear fairly frequently in the automated testing once the keyring was actually used. The problem shows up with some additional debug messages: Gkr: received an invalid, unencryptable, or non-utf8 secret Gkr: call to daemon returned an invalid response: (null).(null)() It seems that sometimes setting up a session with GNOME keyring fails such that all further communication leads to decoding problem. There is an internal method to reset the session, but it cannot be called directly. As a workaround, fake the death of the GNOME keyring daemon and thus trigger a reconnect when retrying the GNOME keyring access. This is done by sending a D-Bus message, which will also affect other clients of GNOME keyring, but hopefully without user-visible effects. * config: enhanced password handling It is possible to configure a plain username/password combination once in SyncEvolution and then use references to it in other configurations, instead of having to set (and update) the credentials in different places. This is useful in particular with WebDAV, where credentials had to be repeated several times (target config, in each database when used as part of SyncML) or when using a service which requires several configs (Google via SyncML and CalDAV). To use this, create a sync config for a normal peer or a dedicated config just for the credentials, with “username/password/syncURL” set. The “syncURL” must be set to something identifying the peer if GNOME Keyring is used for the password storage. Then set “username”, “databaseUser” and “proxyUser” properties to “id:
” and all read and write access to those properties will be redirected by SyncEvolution into that other configuration. This even works in the GTK UI. For user names which contain colons, the new “user: ” format must be used. Strings without colons are assumed to be normal user names, so most old configurations should continue to work. signon: new backend using libgsignond-glib + libaccounts-glib The code works with gSSO (https://01.org/gsso) and Ubuntu Online Accounts.
GOA: get OAuth2 tokens out of GNOME Online Accounts “username = goa:…” selects an account in GOA and retrieves the OAuth2 token from that.
WebDAV: support OAuth2 If given an authentication configuration which can handle OAuth2, then OAuth2 is used instead of plain username/password authentication.
WebDAV: support Google CardDAV, break Yahoo Google CardDAV has one peculiarity: it renames new contacts during PUT without returning the new path to the client. See also http://lists.calconnect.org/pipermail/caldeveloper-l/2013-July/000524.html SyncEvolution already had a workaround for that (PROPGET on old path, extract new path from response) which happened to work. This workaround was originally added for Yahoo, which sometimes merges contacts into existing ones. In contrast to Yahoo, Google really seems to create new items. Without some server specific hacks, the client cannot tell what happened. Because Google is currently supported and Yahoo is not, let’s change the hard-coded behavior to “renamed items are new”.
WebDAV: started testing with owndrive.com = OwnCloud
WebDAV: avoid segfault during collection lookup Avoid referencing pathProps->second when the set of paths that PROPFINDs returns is empty. Apparently this can happen in combination with Calypso.
CalDAV: more workarounds for Google CalDAV + unique IDs Google became even more strict about checking REV. Tests which reused a UID after deleting the original item started to fail sometime since middle of December 2012.
CalDAV: work around Google server regression (undeclared namespace prefix in XML) Google CalDAV for a while (December 2012 till January 2013) sent invalid XML back when asked to include CardDAV properties in a PROPFIND. This got rejected in the XML parser, which prevents syncing calendar data: Neon error code 1: XML parse error at line 55: undeclared namespace prefix In the meantime Google fixed the issue in response to a bug report via email. But the workaround, only asking for the properties which are really needed, still makes sense and thus is kept.
WebDAV: auto-discovery fix With Google Contact + CardDAV the auto-discovery failed after finding the default address book, without reporting that result.
WebDAV: don’t send Basic Auth via http proactively ([FDO #57248](https://bugs.freedesktop.org/show_bug.cgi?id=57248)) Sending basic authentication headers via http is insecure. Only do it proactively when the connection is encrypted and thus protects the information or when the server explicitly asks for it.
file backend: sub-second mod time stamps Change tracking in the file backend used to be based on the modification time in seconds. When running many syncs quickly (as in testing), that can lead to changes not being detected when they happen within a second. Now the file backend also includes the sub-second part of the modification time stamp, if available. This change is relevant when upgrading SyncEvolution: most of the items will be considered “updated” once during the first sync after the upgrade (or a downgrade) because the revision strings get calculated differently.
GTK UI: fixed two crashes - running a sync with no service selected and a 64 bit pointer problem recently discovered by Tino Keitel when compiling the Debian package with -fPIE.
packaging: compatible with EDS up to and including 3.10 and both libical.so.0 and libical.so.1 The binary packages now contain different versions of syncecal.so and syncebooks.so to cover different combinations of EDS and libical.
libical: compatibiliy mode for libical.so.0 and libical.so.1 libical 1.0 broke the ABI, leading to libical.so.1. The only relevant change for SyncEvolution is the renumbering of ICAL_*_PROPERTY enum values. We can adapt to that change at runtime, which allows us to compile once with libical.so.0, then patch executables or use dynamic loading to run with the more recent libical.so.1 if we add 1 to the known constants.
packaging: fix rpm ([FDO #73347](https://bugs.freedesktop.org/show_bug.cgi?id=73347)) After installing the syncevolution.org rpm on OpenSUSE, SyncEvolution was not starting because its shared libraries were not found unless “ldconfig” was called manually. Now the package does that automatically.
packaging: fix description The syncevolution-bundle description of both rpm and deb packagesaccidentally used the same description as syncevolution-evolution.
glib: fix double-free of source tags glib 2.39.0 (aka GNOME 3.10) as found in Ubuntu Trusty introduces warnings when g_source_remove() is passed an unknown tag. SyncEvolution did this in two cases: in both, the source callback returned false and thus caused the source to be removed by the caller. In that case, the explicit g_source_remove() is redundant and must be avoided. Such a call is faulty and might accidentally remove a new source with the same tag (unlikely though, given that tags seem to get assigned incrementally). The only noticable effect were additional error messages with different numbers: [ERROR] GLib: Source ID 9 was not found when attempting to remove it * EDS: fix compile problem with boost and EDS > 3.36 This fixes the following problem, seen with Boost 1.53.0 on altlinux when compiling for EDS >= 3.6: /usr/include/boost/smart_ptr/shared_ptr.hpp: In instantiation of ‘typename boost::detail::sp_array_access
::type boost::shared_ptr ::operator const [with T = char*; typename boost::detail::sp_array_access ::type = void; std::ptrdiff_t = long int]’: src/backends/evolution/EvolutionSyncSource.cpp:163:38: required from here /usr/include/boost/smart_ptr/shared_ptr.hpp:663:22: error: return-statement with a value, in function returning ‘void’ [-fpermissive] make[2]: *** [src/backends/evolution/src_backends_evolution_syncecal_la-EvolutionSyncSource.lo] EDS contacts: avoid unnecessary DB writes during slow sync Traditionally, contacts were modified shortly before writing into EDS to match with Evolution expectations (must have N, only one CELL TEL, VOICE flag must be set). During a slow sync, the engine compare the modified contacts with the unmodified, incoming one. This led to mismatches and/or merge operations which end up not changing anything in the DB because the only difference would be removed again before writing.
EDS contacts: read-ahead cache Performance is improved by requesting multiple contacts at once and overlapping reading with processing. On a fast system (SSD, CPU fast enough to not be the limiting factor), testpim.py’s testSync takes 8 seconds for a “match” sync where 1000 contacts get loaded and compared against the same set of contacts. Read-ahead with only 1 contact per query speeds that up to 6.7s due to overlapping IO and processing. Read-ahead with the default 50 contacts per query takes 5.5s. It does not get much faster with larger queries.
PBAP: add support for obexd 0.47, 0.48 and Bluez 5 obexd 0.48 is almost the same as obexd 0.47, except that it dropped the SetFilter and SetFormat methods in favor of passing a Bluex 5-style filter parameter to PullAll.
PBAP: various enhancements for efficient caching of contacts
HTTP server: handle message resends If a client gave up waiting for the server’s response and resent its message while the server was still processing the message, syncing failed with “protocol error: already processing a message” raised by the syncevo-dbus-server because it wasn’t prepared to handle that situation. The right place to handle this is inside the syncevo-http-server, because it depends on the protocol (HTTP in this case) whether resending is valid or not. It handles that now by tracking the message that is currently in processing and matching it against each new message. If it matches, the new request replaces the obsolete one without sending the message again to syncevo-dbus-server. When syncevo-dbus-server replies to the old message, the reply is used to finish the newer request.
engine: prevent timeouts in HTTP server mode HTTP SyncML clients give up after a certain timeout (SyncEvolution after RetryDuration = 5 minutes by default, Nokia e51 after 15 minutes) when the server fails to respond. This can happen with SyncEvolution as server when it uses a slow storage with many items, for example via WebDAV. In the case of slow session startup, multithreading is now used to run the storage initializing in parallel to sending regular “keep-alive” SyncML replies to the client. By default, these replies are sent every 2 minutes. This can be configured with another extensions of the SyncMLVersion property: SyncMLVersion = REQUESTMAXTIME=5m Other modes do not use multithreading by default, but it can be enabled by setting REQUESTMAXTIME explicitly. It can be disabled by setting the time to zero. The new feature depends on a libsynthesis with multithreading enabled and glib >= 2.32.0, which is necessary to make SyncEvolution itself thread-safe. With an older glib, multithreading is disabled, but can be enabled as a stop-gap measure by setting REQUESTMAXTIME explicitly.
Various testing and stability enhancements. SyncEvolution had to be made thread-safe for the HTTP timeout prevention.
Nokia: always add TYPE=INTERNET to EMAIL ([FDO #61784](https://bugs.freedesktop.org/show_bug.cgi?id=61784)) Without the explicit TYPE=INTERNET, email addresses sent to a Nokia e51 were not shown by the phone and even got lost eventually (when syncing back). This commit ensures that the type is set for all emails sent to any Nokia phone, because there may be other phones which need it and phones which don’t, shouldn’t mind. This was spot-checked with a N97 mini, which works fine with and without the INTERNET type. This behavior can be disabled again for specific Nokia phones by adding a remote rule which sets the addInternetEmail session variable to FALSE again. Non-Nokia phones can enable the feature in a similar way, by setting the variable to TRUE.
SyncML: config option for broken peers Some peers have problems with meta data (CtCap, old Nokia phones) and the sync mode extensions required for advertising the restart capability (Oracle Beehive). The default in SyncEvolution is to advertise the capability, so manual configuration is necessary when working with a peer that fails in that mode. Because the problem occurs when SyncEvolution contacts the peers before it gets the device information from the peer, dynamic rules based on the peer identifiers cannot be used. Instead the local config must already disable these extra features in advance. The “SyncMLVersion” property gets extended for this. Instead of just “SyncMLVersion = 1.0” (as before) it now becomes possible to say “SyncMLVersion = 1.0, noctcap, norestart”. “noctcap” disables sending CtCap. “norestart” disables the sync mode extensions and thus doing multiple sync cycles in the same session (used between SyncEvolution instances in some cases to get client and server into sync in one session). Both keywords are case-insensitive. There’s no error checking for typos, so beware! The “SyncMLVersion” property was chosen because it was already in use for configuring SyncML compatibility aspects and adding a new property would have been harder.
ActiveSync: added support for specifying folder names Previously, the database field was interpreted as a Collection ID. This adds logic to allow the database to be interpreted as a folder path. The logic is: 1) If the database is an empty string, pass it through (this is the most common case as it is interpreted as “use the default folder for the source type”). 2) If the database matches a Collection ID, use the ID (this is the same as the previous behaviour). 3) If the database matches a folder path name, with an optional leading “/”, use the Collection ID for the matching folder. 4) Otherwise, force a FolderSync to get the latest folder changes from the server and repeat steps 2 and 3 5) If still no match, throw an error.
ActiveSync: support for listing databases Now –print-databases scans folders on the ActiveSync server and shows suitable folders for the ActiveSync backends instead of the previous, hard-coded help text. Invoking –print-databases can be used as a workaround for “SyncFolder error: Invalid synchronization key” errors. A better solution would be to do that automatically, but there was no time to implement that. See [FDO #61869](https://bugs.freedesktop.org/show_bug.cgi?id=61869) and “[SyncEvolution] Activesync server losing state” http://thread.gmane.org/gmane.comp.mobile.syncevolution/4295
SyncML: workarounds for broken peers Some peers have problems with meta data (CtCap, old Nokia phones) and the sync mode extensions required for advertising the restart capability (Oracle Beehive). Because the problem occurs when SyncEvolution contacts the peers before it gets the device information from the peer, dynamic rules based on the peer identifiers cannot be used. Instead the local config must already disable these extra features in advance. The “SyncMLVersion” property gets extended for this. Instead of just “SyncMLVersion = 1.0” (as before) it now becomes possible to say “SyncMLVersion = 1.0, noctcap, norestart”. “noctcap” disables sending CtCap. “norestart” disables the sync mode extensions and thus doing multiple sync cycles in the same session (used between SyncEvolution instances in some cases to get client and server into sync in one session). Both keywords are case-insensitive. There’s no error checking for typos, so beware! The “SyncMLVersion” property was chosen because it was already in use for configuring SyncML compatibility aspects and adding a new property would have been harder.
engine: local cache sync mode This patch introduces support for true one-way syncing (“caching”): the local datastore is meant to be an exact copy of the data on the remote side. The assumption is that no modifications are ever made locally outside of syncing. This is different from one-way sync modes, which allows local changes and only temporarily disables sending them to the remote side. Another goal of the new mode is to avoid data writes as much as possible. This new mode only works on the server side of a sync, where the engine has enough control over the data flow. Setting “sync” to: - “local-cache-incremental” will do an incremental sync (if possible) or a slow sync (otherwise). This is usually the right mode to use, and thus has “local-cache” as alias. - “local-cache-slow” will always do a slow sync. Useful for debugging or after (accidentally) making changes on the local side. An incremental sync will ignore such changes because they are not meant to happen, aren’t checked for to improve performance and thus will leave client and server out-of-sync! Both modes are recorded in the sync report of the local side. The target side is the client and records the normal “two-way” or “slow” sync modes. With the current SyncEvolution contact field list, first, middle and last name are used to find matches for contacts. For events, tasks and memos, time, summary and description are used.
Minor memory leak fix when using GDBus GIO: GDBusMethodInfo Also depends on a glib fix, see [BGO #695376](https://bugzilla.gnome.org/show_bug.cgi?id=695376)
build fixes Avoid -lrt in make dependencies. Add missing pcre libs to syncevo-dbus-server. sqlite backend needs “#include <stdio.h>” (patch from Mario Kicherer).
autotools: fix temp file vulnerability during compilation ([CVE-2014-1639](http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-1639)) We must use the temporary file that was created for us securily, not a temp file named after that file. This caused a temp file vulnerability and the real temporary files were not deleted by the script.
workarounds for warnings from g++ 4.5
Upgrading from releases <= 1.3.99.4:#
If the value of “username/databaseUser/proxyUser” contains a colon, the “user:” prefix must be added to the value, to continue treating it like a plain user name and not some reference to an unknown identity provider (like “id:”, “goa:”, “signon:”, etc.). The lookup of passwords in GNOME Keyring was updated slightly in 1.3.99.5. It may be necessary to set passwords anew if the old one is no longer found.
Upgrading from release 1.2.x:#
The sync format of existing configurations for Mobical (aka Everdroid) must be updated manually, because the server has encoding problems when using vCard 3.0 (now the default for Evolution contacts): syncevolution –configure \ syncFormat=text/x-vcard \ mobical addressbook The Funambol template explicitly enables usage of the “refresh-from-server” sync mode to avoid getting throttled with 417 ‘retry later’ errors. The same must be added to existing configs manually: syncevolution –configure \ enableRefreshSync=TRUE \ funambol
Upgrading from releases before 1.2:#
Old configurations can still be read. But writing, as it happens during a sync, must migrate the configuration first. Releases >= 1.2 automatically migrates configurations. The old configurations will still be available (see “syncevolution –print-configs”) but must be renamed manually to use them again under their original names with older SyncEvolution releases.
SyncEvolution 1.3.99.7 -> 1.4#
Compared to the pre-release, 1.4 mostly just enhanced the testing. Compatibility with GNOME 3.10 and a glib-related issue that existed almost forever without causing obvious problems were fixed. syncevolution.org binaries now finally work with distros using libical.so.1 (for example, Ubuntu Saucy and Trusty). Details:
autotools: fix temp file vulnerability during compilation (CVE-2014-1639) We must use the temporary file that was created for us securily, not a temp file named after that file. This caused a temp file vulnerability and the real temporary files were not deleted by the script.
glib: fix double-free of source tags glib 2.39.0 (aka GNOME 3.10) as found in Ubuntu Trusty introduces warnings when g_source_remove() is passed an unknown tag. SyncEvolution did this in two cases: in both, the source callback returned false and thus caused the source to be removed by the caller. In that case, the explicit g_source_remove() is redundant and must be avoided. Such a call is faulty and might accidentally remove a new source with the same tag (unlikely though, given that tags seem to get assigned incrementally). The only noticable effect were additional error messages with different numbers: [ERROR] GLib: Source ID 9 was not found when attempting to remove it
libical: compatibiliy mode for libical.so.0 and libical.so.1 libical 1.0 broke the ABI, leading to libical.so.1. The only relevant change for SyncEvolution is the renumbering of ICAL_*_PROPERTY enum values. We can adapt to that change at runtime, which allows us to compile once with libical.so.0, then patch executables or use dynamic loading to run with the more recent libical.so.1 if we add 1 to the known constants.
Source, Installation, Further information#
Source code bundles for users are available in http://downloads.syncevolution.org/syncevolution/sources and the original source is [the git repositories](http://cgit.freedesktop.org/SyncEvolution/). i386, lpia and amd64 binaries for Debian-based distributions are available via the “stable” syncevolution.org repository. Add the following entry to your /apt/source.list:
deb http://downloads.syncevolution.org/apt stable main Then install “syncevolution-evolution”, “syncevolution-kde” and/or “syncevolution-activesync”. These binaries include the “sync-ui” GTK GUI and were compiled for Ubuntu 10.04 LTS (Lucid), except for ActiveSync binaries which were compiled for Debian Wheezy, Ubuntu Saucy and Ubuntu Trusty. The packages mentioned above are meta-packages which pull in suitable packages matching the distro during installation. Older distributions like Debian 4.0 (Etch) can no longer be supported with precompiled binaries because of missing libraries, but the source still compiles when not enabling the GUI (the default). The same binaries are also available as .tar.gz and .rpm archives in [the download directories](http://downloads.syncevolution.org/syncevolution/). In contrast to 0.8.x archives, the 1.x .tar.gz archives have to be unpacked and the content must be moved to /usr, because several files would not be found otherwise. After installation, follow the [getting started](/documentation/getting-started) steps. More specific [HOWTOs](/wiki/howto) can be found in the Wiki.
